Single-room heat recovery units in Wiltshire

A single-room heat recovery unit is a compact through-wall fan that supplies and extracts air for one room while recovering much of the heat from the outgoing air. It is the answer when one bedroom, kitchen or flat has a condensation problem but whole-home ducting is not practical.

Our team is based in Great Barr, Birmingham, and we work throughout Wiltshire, from Calne, Westbury, Swindon, Salisbury and Trowbridge. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

Some alternate direction every minute or so, storing heat in a ceramic core; others run supply and extract side by side through a small exchanger. Either way, the room gets fresh air without the heat loss of an open window. They are popular in flats, in north-facing bedrooms where mould keeps coming back, and in rooms with no route for ducting.
